Haller Castle, Manor castle in Ogra, Romania

Haller Castle is a manor house in Ogra featuring classicist baroque architecture with vaulted wall structures and a wine cellar beneath the main building. The structure includes 14 rooms furnished with period pieces and equipped with various facilities.

The castle's foundations date from the 17th century, and its wine cellar is the only surviving part of that original residence. The present building was constructed between the 18th and 19th centuries in a post-Baroque style. It was nationalized in 1949 and housed a school, a boarding school and the local council during the communist period. After being returned to the Haller family, it was sold to the Fóris family of Târgu Mureș and has operated as a guesthouse, restaurant and wine cellar since 2011.

The castle is listed as a historic monument under code MS-II-m-A-15737 in Romania's register of monuments. Its wine cellar is the surviving trace of the original 17th-century residence, predating the 18th- and 19th-century building above it. Today the site operates as a guesthouse, restaurant and wine cellar, so visitors eat and stay within the former Haller property.

The castle is located about 22 kilometers from Târgu Mureș and features a restaurant with Transylvanian cuisine and conference facilities. Visitors will also find recreational areas with wellness amenities on the grounds.

The wine cellar is the only surviving part of the original 17th-century residence; the rest of the building dates from the 18th–19th centuries. The castle is listed as a historic monument under code MS-II-m-A-15737.
